`a_(n)=(n-1)(2-n)(3+n)` , find `a_(1),a_2,a_3`

If n^(th) terms of the sequence {a_(n)} where a_(n)=(-1)^(n-1)5^(n+1) , find a_(1),a_(2) , and a_(3) is

Find the terms indicated in each case: (i) a_(n)=4n-3,a_(17),a_(24) (ii) a_(n)=(n-1)(2-n)(3+n),a_(1),a_(2),a_(3)

Find the indicated terms in each of the following sequences whose nth terms are: a_(n)=5_(n)-4;a_(12) and a_(15)a_(n)=(3n-2)/(4n+5);a+7 and a_(8)a_(n)=n(n-1);a_(5)anda_(8)a_(n)=(n-1)(2-n)3+n);a_(1),a_(2),a_(3)a_(n)=(-1)^(n)n;a_(3),a_(5),a_(8)

If a_(n)=(n^(2))/(3n+2) , find a_(1)a_(5) .

A sequence is defined as follows : a_(a)=4, a_(n)=2a_(n-1)+1, ngt2 , find (a_(n+1))/(a_(n)) for n=1, 2, 3.

The Fibonacci sequence is defined by 1=a_(1)=a_(2) and a_(n)=a_(n-1)+a_(n-2),n>2 Find (a_(n+1))/(a_(n)),f or n=5
